Attributes.GetByName() throws Runtime-Error

[JuergenA]

Hi,

if I call the method to find an attribute of a class by its name I get the following error code:

  ?err.Number
  -2147221504
  ?err.Description
  Action is not supported

The attribute name and the class does exist, but
?class.IsNew says "true".

Any hint?

thx,
 Juergen

Code:

Dim aAttr As EA.Attribute
Dim aClass As EA.Element
...
sAttrName="existing_attribute_name"
aClass.Attributes.GetByName(sAttrName)
... -> error!
